Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a covering material having excellent weather-resistance and effective for promoting or suppressing the plant extension and growth. SOLUTION: This covering material is produced by laminating an acrylic resin containing an ultraviolet absorber having 250-400 nm maximum absorption wavelength on a substrate having ≥50% transmittance of photosynthetic photon flux in transmission of natural light and 1.3-3 A-value defined by the formula A=R/Fr (wherein, R is a photon flux of red light of 600-700 nm wavelength; and Fr is a photon flux of infrared light of 700-800 nm wavelength).
